Specific embodiment
It should be noted that in the absence of conflict, the feature in embodiment and embodiment in the present invention can phase
Mutually combination.
The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
The present embodiment is related to a kind of Wiring harness terminal crimping molding structure, as shown in fig. 1 comprising conducting wire 1 and is crimped on
Wiring harness terminal 2 on conducting wire 1, conducting wire 1 and Wiring harness terminal 2 constitute crimping structural body after molding.Structure in the present embodiment
The structural parameters of ontology include width W and height H, further include two evaginations that Wiring harness terminal 2 is formed by crimping and symmetrical cloth
The arc radius R for the small arc-shaped 3 set1, two small arc-shapeds 3 are specifically made of the arc section of Wiring harness terminal 2.
The parameter that structural body after molding is crimped in the present embodiment is still further comprised relative to two small arc-shapeds, and
The arc radius R of the orthodrome 4 for the evagination that the other side of structural body is formed2, and with orthodrome 4 it is located at the same side, it is right
Claim the width L of arrangement and two platforms 5 close to the width edge edge of structural body, orthodrome 4 is the platform 5 for being connected to two sides
Between.As shown in fig. 1 in the present embodiment, structural body demoulds de- after the two sides of structural body are also formed with convenient for crimping
Mode structure face 6, the draft angle α in demolding structure face 6 are also a part of structural body parameter.
The width W and height H of structural body are directed in the present embodiment, to guarantee the configuration symbol after Wiring harness terminal 2 crimps
It closes and requires, according to golden section point, be between width W and height HTo height H=0.618W.And for width
W is spent, can be considered by W*H after crimping and S1+S2* 0.75 is equal, wherein S1For the cross-sectional area of Wiring harness terminal 2, and Wiring harness terminal 2
Cross-sectional area S1Compression ratio in crimping is negligible, S2It is then the cross-sectional area of conducting wire 1, and the cross-sectional area of conducting wire 1
S2Compression ratio in crimping is 75%.The width of structural body to known to
It is guarantee Wiring harness terminal 2 in the present embodiment during crimping, it will not be because the arc section of Wiring harness terminal 2 be because of too early phase
It hands over and terminal is caused to touch wall, cause the intersection of terminal circular arc to have the gap because intersecting too late, or cause to bottom out because that cannot intersect,
Therefore the angle that two arc sections intersection of small arc-shaped 3 is formed on Wiring harness terminal 2 is separated with golden section rule, specifically may be used
As shown in Figure 2, the arc section of two intersections on Wiring harness terminal 2 is represented with two complete and intersection circles in Fig. 2, each circle
The arc radius R of radius, that is, small arc-shaped 31, two round distance of center circle O are also the distance of center circle O of two small arc-shapeds 3, according to gold
Separate rule, ∠ a=90 ° * 0.618=55.6 °, ∠ b=∠ c=90 ° * (1-0.618)=33.4 ° in Fig. 2.
As shown in Figure 2, and because of W=O+2R1,Therefore know the circle of small arc-shaped 3
Arc radiusAnd the distance of center circle of two small arc-shapeds 3 is thenIn the present embodiment
Platform 5 is set and carries out burr occur when limitation can effectively avoid terminal compression joint to the width L of platform 5, and can be delayed
To the impact force of press-connection machine lower jaw when punching press connects.The width L of platform 5 is set asWherein h is Wiring harness terminal
Thickness.It can avoid L according to this to be arranged smaller and structural body is caused to be easy to appear burr or the larger thickness for making Wiring harness terminal 2 of L
Be extruded it is thinning, thus easily cause Wiring harness terminal 2 crimp after bottom there is slight crack, influence Wiring harness terminal 2 crimp after reliability.
For the arc radius R of orthodrome 4 in the present embodiment2, as shown in Figure 3, two roundlets still indicate roundlet in Fig. 3
Arc 3, and one section of circular arc for being located at two roundlet sides then represents orthodrome 4, it is symmetrical after Wiring harness terminal 2 crimps to guarantee, therefore
The center of circle of orthodrome 4 should be in the symmetrical center line of the circle center line connecting of two small arc-shapeds 3, and the center of circle of orthodrome 4 should also be located at
On the common tangent on the two roundlet top namely center of circle of orthodrome 4 is the A point in Fig. 3.In addition, to guarantee that Wiring harness terminal 2 crimps
It does not bottom out in the process, touch wall, orthodrome 4 also should be tangent with the outside of two roundlets, and the position at point of contact also should be through excessive
Straight line is done in the center of circle A of circular arc 4 and the center of circle (being indicated in Fig. 3 with C) of small arc-shaped 3, which intersects with orthodrome 4, intersection
Intersection point is the point of contact of orthodrome 4 Yu roundlet, which is indicated in Fig. 3 with B.
By foregoing description and Fig. 3 is combined, therefore the arc radius R of orthodrome 42For the distance of A, B point-to-point transmission, and according to A, D two
Point the distance between beC, the distance between D two o'clock is R1, therefore the distance between A, C two o'clock isInto
The arc radius of the distance between A, B two o'clock namely orthodrome 4 known to one step
The draft angle α in demolding structure face 6 is set as 3 °~5 ° in the present embodiment, and preferably draft angle α is 4 °, presses at this time
Connecing structural body after molding can be easy to carry out stripping operation.The Wiring harness terminal crimping molding structure of the present embodiment, passes through conducting wire 1
And each structural parameters setting of the structural body that is constituted of Wiring harness terminal 2, it is ensured that Wiring harness terminal 2 crimps section with conducting wire 1
Meet the requirements so that have preferable crimping quality after the crimping molding of Wiring harness terminal 2, meet Wiring harness terminal 2 and conducting wire 1 it
Between connection request.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
